Types Of Mother Board

The motherboard is the main component, based on its function, of the internal structure of all computers. Mainly responsible for the interaction of all the elements of the computer, such as the CPU, RAM, storage, graphics card, I/O, among others.

It is extremely important to recognize its capabilities, limitations as well as the main features it contains so as not to repress the potential of any other piece within the PC. Another key element is the form-factor (exterior physical size and shape) which also should be considered for the computer application according to the field where it’ll be used.

Motherboards are always characterized by their chipset, type of processor socket, and their form factor.

The following is a picture showing the most important Motherboard Components.  The motherboard in the picture is the PRO and its components are:

• CPU and CPU socket.
• RAM, DRAM, and RAM slots.
• ATX power supply.
• IDE Connectors
• Northbridge and southbridge.
• AGP Slot
• PCI Slots.
• CMOS Backup Battery
• Integrated connectors for peripherals such as USB, mouse, keyboard, display, audio, Ethernet, etc.

Form Factor ATX (Advanced Technology Extended)

Designed as an evolution of the Form Factor. ATX marks a profound change in the architecture of the motherboard and other components such as the cabinet and the power supply.

Within the motherboard there are significant changes such as the location of the CPU socket, which is now placed near the power supply, thus allowing the flow of air caused by the fan of the source and not to be interfered with by any element as it happened with the technology Baby AT.

Another change was the connection between the source of the feed. Which is now a single connector, unlike the AT which were two. Some of the most important improvements for ATX and benefits are:

• Integrated input and output ports
• Slots of expansion without interference
• Start Control by software
• 3 Vol. from the source (reduces hardware cost, energy consumption, and heat)
• A better airflow
• Less interference in access to drive bays.

The ATX motherboard dimensions are 12 × 13 in. A variation of the ATX is the Mini ATX, which is essentially a reduced-size version of ATX but more reduced in terms of its shape, its measurements are 11.2 × 8.2 inches.

This form factor is the most used today, especially on desktop computers, and after this technology was released several other factors where based on it. Such as the Mini-ITX, Mini-ATX, Micro-ATX, Nano ITX, and Pico-ITX.

Micro ATX

It is an evolution of ATX. Its measures are 9.6 × 9.6 inches. The Micro-ATX supports up to four expansion slots that can combine freely with ISA, PCI, PCI / ISA shared, and AGP. Mounting holes changed from the Standard ATX, since the measurements are different, but they are also compatible with most ATX cabinets.

This type of motherboard form factor supports both Intel and AMD processors. It is commonly used on Small Form Factor Desktop Computers.

Mini-ITX

Mini ITX is a low-power consumption motherboard format of 6.7 × 6.7 inches. Its dimensions are the most characteristic factor of this type of form factor. Although this type of motherboard was designed with the aim of empowering teams of low consumption, at present there are no limits and they have grown by giant steps in terms of benefits.

Since the Mini-ITX was introduced they have expanded in all kinds of applications, thanks to their open standard factor. Mini ITX is a standard format for all types of equipment, such as vehicle embedded computers, industrial applications, and IoT. The Mini-ITX is the first standard system of reduced format that is popularized, reaching all types of projects and any equipment where it may be necessary.

Nano-ITX

The Nano-ITX is another type of motherboard form factor, that measures 4.7 × 4.7 in. Nano-ITX are fully integrated boards designed to consume very low power. This type of motherboard can be used in many applications, but it was specially designed for smart entertainment, like PVRs, media centers, smart TVs, in-vehicle devices, and more.

Pico-ITX

The Pico-ITX is the smallest type of motherboard form factor in this list. Its measurements are 3.9 × 2.8 in and it is 75% smaller than the Mini-ITX. This motherboard was designed and developed by VIA, to open up innovation for smaller and smarter IoT devices.

The Pico-ITX with an x86-based-platform and low-power consumption board is a great choice for embedded systems applications, such as industrial automation, in-vehicle computers, digital signage, and more.
